Unable to connect to my own system through SSH

Solution 1:

Loging into a system as root is generally considered to be a bad thing. You will probably find that the that sshd is denying root logins. Check /etc/ssh/sshd_config for the line

PermitRootLogin no

Changing no to yes and restarting sshd would allow root to log in. This is however a bad idea. You should connect as a normal user and use sudo or su to perform administrative tasks.

The IP address you have is an address from one of the private address blocks.

Solution 2:

Most linux systems will not permit root to connect to ssh. look for the line

PermitRootLogin no

in file /etc/ssh/sshd_config

I'd opt to use a less privileged user if you can.
